The Detecto 4420 Bench Scale is designed for the rugged industrial or tough shipping and receiving environments where high accuracy and minimum maintenance are necessary. The heavy duty welded steel base will stand up under the most rigorous use and still provide long term accuracy to 4 ounces. The scale's accuracy is further enhanced by its presision die-cast weighbeam which is easily read from both sides. Special tip locks and checks prevent the platform from tipping, protecting pivots and bearings. Each scale receives a tough mar-resistant finish to protect the scale for years to come.
